removing "metallic echo" from audio?

[rowie4life]

I removed the hiss from a audio file but now i can hear a "metallic echo" type noise.
I'm using Nero WaveEditor 3. Is there a way to reduce/remove it?

It sounds like you over filtered to remove the hiss. I would start again with original audio track and use audacity instead.

I used Audacity (on the same audio file) and the same "metallic echo" was there, it sounded muffled (had to much bass)

Can you post a short segment of the original to listen to and play with ?

I'd rather hear hiss than the artifacts of hiss removal. It's too hard to do it right. At least for me. But if you just have to remove that hiss, why not try partially removing it rather than going for complete and total hiss-free?

If one can hear this hiss, then the hiss is in a handful of auditable frequencies. To properly take only the hiss out, the audio has to run thru FFT to pinpoint the spectra lines.... then feed thru narrow band pass filters, then... = a lot of work.

This has come from a very heavily compressed source. All the life has been squeezed out of it, and the 'metallic' compression artifacts are very evident before doing any processing. There is, in fact, almost no hiss in the sample, only compression artifacts from being compressed too much.

There really isn't anything useful you can do to this to improve it more than 1 - 2 % Get a less compressed source, or live the (lack of) quality you have.

Sometimes it's about the lesser of evils. Sometimes a small bit of electronic noise is better than the noise that was removed. It all depends. I did not listen to the above clip, by the way.
